LFS doesn't have journaling at all. It can't have journaling because it
is not a journaling FS, it is log structured. (Like NetApps WAFL or
ZFS. Yes, AFAIK ZFS is log structured, not journaled.) Due to the
inherent way LFS works you get the same effect as on a data +
metadata journaling FS: Either the last write succeded and you get the latest data + metadata. Or the last write didn't complete and you get the previous data + metadata.

Well. To be onest. If I had important data on LFS I would ensure to
have a good backup... All I can say is: I tried it at some occasions on
sparc64 and it worked well for me.
